About game
The goal of Sudoku is to fill in a 9 by 9 grid with numbers so that each row, column and 3 by 3 grid contains all the numbers from 1 to 9. Your task is to fill in the missing numbers and fill in the entire grid correctly.
It will be incorrect if:
• Any line contains the same numbers from 1 to 9
• Any column contains the same numbers from 1 to 9
• Any 3×3 grid contains the same numbers from 1 to 9
How to play
The game is controlled using the mouse or by tapping on the screen of a mobile device:
- to enter the desired cell, the cell is selected first;
- after selecting a cell, it is highlighted in yellow and a panel with numbers from 1 to 9 appears on the right of the field;
- you need to select the number that you want to put in the cell;
If all the fields are filled in correctly, then you have solved the Sudoku!
